After selecting these 2744 non-AGN galaxies, we went through the visual
inspection of their images and we further removed those galaxies with
superposed foreground bright stars, and also galaxies with
signs of interactions and mergers. Our final sample of non-active
galaxies contains 2301 sources. Using the visual morphological
classification of [1]} and their T-type classification
scheme (see their Table 1), we have 471 early-type galaxies
(elliptical and lenticular, with T-type \(\le \)  0), 891 early-spirals
(0 \(>\)  T-type \(\le \)  4), 889 late-spirals (4 \(>\)  T-type \(\le \)  8), and 50 irregular and peculiar galaxies (T-type \(>\)  8). We inspected visually the images of those galaxies with T-type \(>\)  8 and found that the majority (\(> 80\%\) )
of them are not irregular galaxies, but rather disturbed galaxies with clear signs of
interactions, and therefore along this paper we will call these
galaxies peculiar. An example of 10 galaxies included under this
class is given in Fig. REF .
